These hardy, versatile plants thrive in poor soil and dry conditions, making them a smart pick for both beginner and experienced gardeners.

Whether you’re growing for visual appeal, companion planting, or edible gardening, planting nasturtium seeds offers beauty and function all season long. Their trailing and bushy varieties also make them great for covering bare patches or cascading from containers.

When to Sow Nasturtium Seeds

Generally, nasturtium seeds are grown from late winter to early summer as flower seeds to sow in spring, allowing them time to establish before the harsher peaks of summer or winter affect these flowers. This will vary across different climate zones; however, they are grown between autumn and early spring for subtropical climates and in the dry season only for tropical climates.

How to Grow Nasturtium Seeds

Your nasturtium seeds will thrive best when grown in a sunny spot, as they require at least three hours of full sun per day. The ground they’re grown in will need to be fertile and well-drained to ensure they grow to be happy and healthy. So, be sure to dig in some well-rotted manure or compost before planting. Avoiding high-nitrogen feeds will promote more flowers in favour of foliage.

During the growing season, they’ll need regular watering when the soil becomes dry. You should also keep on top of any weeds that grow and remove them to prevent competition for resources. Adding an organic mulch, such as sugarcane or straw, can help to make managing both of these easier.

Depending on the variety you choose, your nasturtiums will either sprawl across the ground or climb upwards and require support, such as a wire fence or trellis. Deadhead your nasturtium plants if you want to avoid self-seeding.

Adding Nasturtiums to Your Vegetable Garden

Our top-quality nasturtium plant seeds produce brilliant red, orange, and yellow flowers that not only look fantastic in your growing space but are also highly useful for companion planting.

As a highly beneficial plant, nasturtiums attract pollinators and naturally deter garden pests, allowing your vegetable garden to flourish fully. In particular, they can help prevent pests that would otherwise attack your plants if you’re growing tomato seeds, cucumber seeds, and lettuce seeds.
